- What properties in microorganisms were researchers at SINTEF and NTNU looking for? What made them select Micrococcus luteus as a candidate organism? Describe the steps involved in genetic engineering, prior to commercial production of the potential `UVAblue’ sunscreen. What damage do long wave UV radiations induce in human cells?How can the damage induced by ultraviolet light be repair? Excision repair system Either the excision repair system or the light repair system Light repair system Damage due to ultraviolet light is irreversible None of the answer choices.propose a hypothesis regarding the organism (escherichia, staphylococcus, pseudomonas, bacillus) that will demonstrate greater resistance to UV and why? if the hypothesis is supported, what specific experimental results will be observed? and what serves as the control treatment?
- How many different enzymatic activities are required in human cells to repair the most common damage caused by UV-irradiation?Why is UV-C is more likely to harm DNA than UV-A?One of the early results shows that the post-centrifugation pellet of encapsulated cells also contains EA1 and/or Sap. Why is this not proof that Bacillus anthracis cells have both an S-layer and a capsule simultaneously? I need help finding the answer in the article and explain in short answer link to article: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC106848/
- Which of the following is true of the gel electrophoresis shown? Note: Only one can be true... I'm between c or d. Previous answer confused me more. A) the power source has not been turned on yet. B) the three wells contained the same DNA molecules. C) well #1 had fewer molecules of DNA than well #2 or #3 D) well #3 had more different sized molecules of DNA than well #1 or #2In the more common protocol for immunofluorescence detection of cellular proteins, an investigator uses two antibodies. The first binds specifically to the protein of interest. The second is labeled with fluorochromes for easy visualization, and it binds to the first antibody. In principle, one could simply label the first antibody and skip one step. Why use two successive antibodies?UV-induced DNA Damage and Repair by Photoreactivation Experiment Can you help me regarding on how to compute for the % survival rate and % mortality rate. (You can give random examples for the number of irradiated colonies & number of photoreactivated colonies, I just want to see how it is computed). Thank you
